Be it known that I, SIEGFRIED Sonor- FLOCHER, a subject of the King ofGreat Britain, and resident of 524 Craig street west, in the city anddistrict of Montreal, Province of Quebec, Dominion of Canada, haveinventedcertain new and useful Improvements in Lightfieflectors; and Ido hereby declare that the following is a full, clear, and exactdescription of the same.

The invention relates to improvements in light reflectors, as describedin the present specification and illustrated in' the accompanyingdrawings that form part of the same. 7 a

The invention consists essentially in the novel construction andarrangement of parts, whereby the light from the illuminating member isdiffused by rereflection.

The objects of the invention are to increase the efficiency of lamps,particularly electric lamps, to devise a means of illumination whichwill be especially applicable to displays and to factories or'largeinstitutions, and generally to provide a simple, cheap and durablelighting fixture.

The drawing is a vertical sectional view of the lighting arrangement asapplied to an electric are light. 7

Referring to the drawing, -1 is an arc lamp, here shown as of veryordinary pattern, though it'mustbe understood that it ma be of anysuitable make and further the actual lighting fixture may be of manydifferent forms, besides, other than electric illuminating can be usedwith this-in vention.

2 is a main reflector preferably of arc shape in crosssectionandarranged behind the lamp 1 as customary in lighting fixtures. I

3 is the minor reflector in front of the lamp having the'central portion4; thereof slightly raised and an opening 5 there- 'through, saidreflector being preferably of comparatively flat dish form with the saidraised center.

6 is the glass side, preferably frosted and secured at the outer endthereof to the re- Hector 3 and at the inner end thereof to thereflector 2, though it must be understood that the reflector 3 in frontof the lamp may Specification of hetters Patent,

be simply secured to the reflector 2 by I rods or brackets or in fact inany suitable manner, further, the said reflector-3 may be of differentshape to what is shown herein, so long as it provides properly a doublereflection for the diffusion of the light. 7 is'a glass covering for theopening 5,

this glass being preferably frosted, thoughit will be readily seen thatthis hole through the reflector may be left uncovered, withoutmaterially affecting the advantages of this invention.

' It will be seen from this description that a lamp is provided somewhatin the form of a lantern, in which the arc globe or other globe isinclosed within a casing, said casing comprising the rear and frontreflectors and the glass sides, therefore, the diffusion of the light isparticularly good as the rays are thrown back from the front reflectorto the rear reflector which directs 'them through the glass sides, ofcourse,

these glass sides may not be there, but the d ffusion will be very muchthe same,

though the light itself is naturally softened by the glass. Theonlystraight reflection is through the central hole in the reflector 3,therefore there will be no spotv of darkness immediately under thereflector 3.

The material of thereflectors is prefer- .ably aluminum, as that metalprovides a very even and consequently steady reflection so effica-ciousin lights that are not absolutely steady, further this even and steadyreflection is very advantageous as regards diffusion, and consequentlythe light reflected back from the front reflector, spreads considerablywhen again thrown out from the main reflector.

What I claim as my invention is:

1. In light reflectors, the combination with the lighting member and alarge concave reflector arranged thereabove, of a transparent holdersupported from the outside edge of said reflector and convergingdownwardly and holding at its lower end below the light a smallerreflector adapted to throw the light onto the said upper reflector.

2 In light reflectors, an illuminating member, a circular concavereflector above said member, a, frusto-conical globe supported from theoutside edge of said reflector and converging downwardly, a smallerreflector supported by said 5 edge below the light and globe at itslower adapted to reflect the light onto said upper reflector.
